At any event that you attend, there are people who you know there, among the organizers and in the audience -- or one of the presenters. You would like to have a closer relation to them.
Askyoume enables you to provide useful feedback to them: to the organizers, to the presenters.
Askyoume aggregates feedback. You are doing something effective with your time, enjoying your time, and getting intrinsic rewards. We all have the same amount of time. Using time well is the challenge. Facebook wants your time. But do they have you doing something effective with your time?
Askyoume curates the system. It's based on the Toastmasters system.
